In the ample,the computing device may be conveniently present embodiment of theinvention, the column employed to indicate telephone toll charges bei2is arranged laterally between the longitudinal tween certain cities ortowns and/or the differedges of the strips so that a column I5 extends55 from each end of a space I3. The particular location of the column I2laterally of the strip may, of course, be varied to suit conditions aswill be more fully hereinafter understood.

Each space I3 contains indicia indicating different towns or cities andthe columns I5 are divided into a plurality of squares I6 containingindicia indicating different mileage figures opposite each city or townin the spaces I3. The figures in each column I5 are, of course,predetermined to indicate the mileage between the city or town in theregistering space I3 and other cities or towns applied to a feeler I'I,which is slidably engaged with the strip I after the latter is foldedalong the dividing line II. It will, of course, be understood that thestrip I0 is folded on the dividing line in such a manner that the sidesof the adjacent wall portions carrying the indicia face outwardly.

I'he nder I'I is in the form of a strap extending continuously aroundthe adjacent Wall portions and serves the additional function of holdingthe wall portions in positions adjacent each other. It follows from theabove that the opposite ends of the strap I'I extend across the adjacentlongitudinal edges of the wall portions, with the result that a map orother loose data may be retained between the wall portions, .if desired.

Applied to the outer surface of each side of the strap I'I is a columnIB extending longitudinally ofthe strap and divided into a `plurality ofspaces I9 by lines 20 extending transversely of the strap. The number ofspaces I9 correspond to the number of spaces I6 in any one of thecolumns I and the spaces I 9 are arranged to respectively register withthe spaces I6. Upon reference to Figures 2 and 3, it will be noted thateach space I9 on the strap II contains a city or town and, in thepresent instance, certain of the cities on the strap correspond tocities in the column I 2 on the folder. In this connection, attention isdirected to Figure 2, wherein it will be noted that the city Cleveland,Ohio appears in the column I2 on the folder and in the column I8 on thestrap. Also, the strap is shown in Figure 2 as adjusted tol a positionin registration with Clevland, Ohio in thecolumn I2, and it will beobserved that the space I6, in the column I5 extending from the lattercity and registering with the city Cleveland, Ohio on the strap, is leftblank. This procedure is followed wherever there is a duplication ofcities or towns on the folder and strap.

The construction is such that the distance between any one town in thecolumn I2 and any one of the cities on the strap I'I may be readilyobtained by merely adjusting the strap to a position wherein the topedge 2l of the strap registers with the bottom line i4 of the spaceoccupied by the selected city in the column I2 and reading the mileagefigure in the column I5 opposite the selected city on the strap I'I.

Assuming, for example, that it is desired to determine the distancebetwen Cleveland, Ohio, and Washington, D. C., the operator merelyadjusts the strap Il to register the top edge of the strap with thebottom line I4 of the space in the column I2 occupied by the indiciaCleveland Ohio. After this setting of the strap is accomplished, theaccurate mileage of 361 miles may be read in the column i5 opposite thespace Cleveland, Ohio in the column I2 on the folder and registeringwith the space Washingtom D. C. on the strap. This setting of thecomputing device is illustrated in Figure 2 and it will be understoodthat the distances between any city in the column I2 on either side ofthe folded strip IIJ and the cities on the strap I'I may be readilydetermined by following the same procedure.

It will be apparent from the foregoing that the computing Adevice isextremely simple in construction and does not require the use ofexpensive materials. As a matter of fact, the manufacturing costs of thecomputing device are so low as to permit employing the same as anadvertising feature and when designing the device for this use,suflicient space may be made available at the top edge 23 of both sidesof the device for advertising matter.

Referring now to the embodiment of the invention illustrated in Figures5 to 9, inclusive, it will be noted that the computing device isfashioned from a strip of material 25 having a length greater than thelength of the strip I0 and adapted to be folded along the lines 26, 21and 28. The strip 25 is shown in its folded position in Figure 8 ofthedrawings and it will be observed that folding the strip 25 along thelines previously described provides the device with opposed walls 29 and29 having foldable iiaps 3G and 30 at the upper ends thereof. Theexposed surfaces of the opposed walls are provided with columns ofindicia which, for the purpose` of simplicity, is shown to impart thesame information as the inicia on the opposed wall'portions of thecomputing device previously described in connection with Figures l to 4,inclusive. The arrangement, however, is slightly different in that aco1- umn 3l of cities or towns is arranged on the side wall 29 only ofthe folder and these cities or towns serve to identify the indicia onboth side wall portions of the folder ina manner to be more fully setforth.

Upon reference to Figure 6, it will be noted that a column 32 extendstransversely of the side wall 29 of the folder from each city or town inthe column 3| and additional columns 33 extend transversely of theopposite wall 29', as clearly shown in Figure 7. The columns 33 are, ineffect, continuations of the columns 32 and both columns are dividedinto a plurality of spaces 34` corresponding in number to the number ofcities or towns applied to the opposite sides of the strap 3 5. Eachspace 34 continues a mileage iigure representing the distance betweenany one geographical location in the column 3| and any' one of thelocations on the strap.

As in the rst described form of the invention, the strap 35 extendscontinuously around the side walls of the folder and is capable ofsliding movement relative to the folder in the direction of the column 3I. It may be pointed out that the cities or towns on the strap 35correspond to certain of the cities or towns in the column 3I and, forthis reason, certain of the spaces normally occupied by the mileagefigures are left blank. Assuming that the strap 35 is positioned in themanner shown in Figure 6, wherein the top line of the strap registerswith the space on the folder containing Detroit, Michigan, it will benoted that the mileage space registering with the indicia Detroit,Michigan on the strap is, of course, left blank. This procedure isfollowed wherever there is a duplication of cities or towns on the strapand in the column 3I.

It will also be apparent from Figure 6 that the exposed surfaces of theflaps are provided with indicia. The flap 30 is provided with a column36 arranged as a continuation of the column 3I and divided by transverselines 31 into a plue rality of spaces 38. Arranged in each space 38 is acity or town and registering with each space 38 is a transverse column39 divided into a pluralty of spaces fl. The flap 30 is also providedwith columns 4l forming, in effect, continuations of the columns 39 andalso divided into spaces 40. The number of spaces on the flap 30correspond to the number of locations on the adjacent side of the strap35 and the number of spaces on the flap 30' correspond to the number oflocations on the opposite side of the strap. Arranged in each space 4Dis indicia representing either actual mileage, or some other informativedata in regard to the particular geographic locations listed. In theinterests of simplicity, I have shown actual mileage figures in thespaces 40 so that the flaps may be considered as merely forming acontinuation of the side wall portions of the folder.

In operation, assuming that it is desired to find the distance betweenDetroit, Michigan and Washingtony D. CL, the strap 35 is adjusted toregister the top edge thereof with the city Detroit, Michigan in thecolumn 3| on the side 29. Inasmuch as Washington D. C. appears on theopposite side of the strap, it is necessary to reverse the folder andread the mileage 531 in the column 4l on the side 29' opposite thegeographical location Washington D. C. on the strap. In the event it isdesired to determine the mileage, for example, between Detroit, Michiganand Louisville, Kentucky, the strap is registered With the indiciaDetroit, Michigan in the column 3l on the wall 29 of the folder.Louisville, Kentucky is on the same side of the strap, it is notnecessary to reverse the folder and the mileage 389 may be read directlyopposite the indicia Louisville on the strap.

However, the figures in the spaces 4D may be readily changed to indicatediiferent informative data in regard to the particular geographicallocations listed. For example, these figures may indicate the telephonetoll charges between any one of the cities in the column 36 and thecities on the strap 35, or it is possible to insert indicia In View ofthe fact that the indicia in the spaces 40 imparting the difference inthe time between the geographic points listed in the column 3S and onthe strap 35. Also, the opposed sides of the folder and the flaps may4be employed to indicate different information in regard to the selectedgeographic locations. In other words, one side of the device may be usedto afford information in regard to telephone toll charges and the otherside employed to give the actual mileage. It follows from the above thatVarious changes may be made in either of the two constructions selectedherein for the purpose of illustration without departing from the spiritand scope of this invention.

It will be noted from Figure 8 that the strap 35 not only acts as afinder for the calculating device, but serves to hold the flaps 30 and30 adjacent the side wall portions 2S and 29 when the device is not inuse. In this position of the strap, the device may be employed as afolder to retain a map or other loose data.

What I claim as my invention is:

A computing device comprising a relatively long strip having on one facethereof a column of indicia representing different geographicallocations, said strip beng folded along a transverse line substantiallymidway of the geographical indicia to provide a` folder having indiciaboth on the front and back thereof, and a folded relatively narrowone-piece strap embracing both folds of the strip and having its endssecured together, said folded strap being slidable longitudinally onsaid folder and snugly engaging the longitudinal edges of the folder tohold the folds together, said strap having a column of indicia arrangedtransversely with respect to said firstmentioned column and representinggeographical locations, said folder also having numerical data arrangedin alignment with both the first and second mentioned columns andadapted when one edge of the strap registers with a geographicallocation in the first-mentioned column to indicate a numerical relationbetween the 1ocation in registry with the strap edge and the locationsdesignated in the column on the strap.
